A big advantage of the font family is a consistent width of all sixteen styles, so it is possible to switch between them without changing the typesetting. Tabac Mono extends the means of expression of the other fonts in the font superfamily, with which it shares several OpenType functions, including indexes, fractions, several types of numbers and alternative shapes of the most distinctive letters of the Latin alphabet (a, g, Q), which you can use to significantly influence the character of the final composition.
